A shutter and a photographing apparatus are provided. The shutter includes: a shutter base including an exposure opening; a shutter mechanism including a blade assembly and a synchronizer ring for driving the blade assembly, the synchronizer ring being movable between a first position and a second position, and the exposure opening being open when the synchronizer ring is in the first position and closed when the synchronizer ring is in the second position; and a braking member for decelerating the shutter mechanism. In the shutter and the photographing apparatus according to the present disclosure, the shutter mechanism may be buffered when the blade assembly closes the exposure opening of a camera, so as to prevent the shutter mechanism from being damaged.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The shutter according to claim 1, wherein the synchronizer ring is configured to surround the exposure opening.
3. The shutter according to claim 1, wherein the synchronizer ring includes a limiting protrusion movable between the first position and the second position.
4. The shutter according to claim 1, wherein the braking ring is configured to surround the exposure opening.
5. The shutter according to claim 4, wherein the braking ring is coaxial with the exposure opening and the synchronizer ring.
10. The shutter according to claim 1, wherein the braking member includes at least one friction member to decelerate the shutter mechanism by friction.
11. The shutter according to claim 10, wherein the at least one friction member is arranged on at least one of the shutter base, the braking ring, or the synchronizer ring.
14. The shutter according to claim 13, wherein the at least one biasing member interacts with at least one of the shutter mechanism, or the braking ring.
15. The shutter according to claim 13, wherein the at least one biasing member is arranged on the shutter base.
16. The shutter according to claim 13, wherein a plurality of biasing members are arranged on the shutter base and at equal intervals along a circumferential direction of the shutter base.
